Cable Management – The Big Fight: Perforated VS Wire Mesh Cable Tray

When it comes to cable management, debates over the suitability of one solution over another are commonplace, but when it comes to the pros and cons of perforated cable tray in relation to wire mesh things can become heated. In order to get a balanced view on the subject Electrical Review spoke to Nigel Leaver, a marketing manager in Legrand’s cable management division, which manufactures and sells both products

Tracking the perforated tray versus wire mesh debate back to its origin is relatively straight forward, with it all beginning when wire mesh first squared up to perforated tray with a view to grabbing market share and establishing itself as the solution of choice.
Ever since, this battle between the new kid on the block and the traditional old master has demanded industry atten[……]

Structured Cabling – 10 Easy to Avoid Mistakes

With such an array of technologies available in cabling today, it is easy to be confused by your options when having network cabling installed. This article should give you a few tips to help you avoid making costly mistakes.

Take a look into the future.

While Cat5 cabling may be the less expensive route, but it’s important to think about the future of your telecommunications system. With this being said, it’s wise not to install anything less than Cat5e cabling. It is also smart to install cabling that will give you[……]

Open Wire Management – Wire Mesh Cable Tray vs. Conduit

wire mesh cable management systems

Building construction has failed to keep pace with productivity improvements found in other segments of the economy. According to the U.S. Bureau of Labor Statistics, nonfarm (manufacturing) productivity has improved 200 percent since 1964 while construction productivity has actually declined. Studies also indicate that only about one-third of the working day is physical, hands-on installation and testing. The rest is overhead activities associated with installation or nonproductive time such as breaks, cell phone use, and so forth. Whatever the causes of lost or unproductive time, electrical contractors must identify new methods that will improve productivity and remove impediments to success.

As an alternative to traditional conduit, one of the best and most innovative methods is to[……]

What NEC states for max. voltage drop?

The NEC states in an Informational Note that a maximum voltage drop of 3% for branch circuit conductors, and 5% for feeder and branch circuit conductors together, will provide reasonable efficiency of operation for general use circuits.

For sensitive electronic loads, circuits should be designed for a maximum of 1.5% voltage drop for branch circuits at full load, and 2.5% voltage drop for feeder and branch circuits combined at full load.

Four practical approaches can be used to minimize voltage drop problems:

  1. Increasing the number or size of conductors
  2. Reducing the load current on the circuit
  3. Decreasing conductor length, and
  4. Decreas[……]
